Abstract: PROBLEM TO BE SOLVED: To excellently perform the patterning of a metal electrode layer without using metal mask by forming a transparent electrode layer on a substrate, a soluble layer at a position corresponding to a groove, an insulating layer on the substrate, a picture element opening and groove opening in the insulating layer, a groove for patterning metal electrode while dissolving the dissolved layer, and a light emitting layer in the picture element area in order, and thereafter, forming plural divided metal electrodes in the groove. SOLUTION: A transparent electrode layer 2 is formed on a transparent substrate 6 by patterning, and an insulating film layer 109 is formed thereon by etching while using polyimide. A mask formed with an opening corresponding to a groove 107 is arranged at the predetermined position of the insulating film layer 109, and a groove is formed by the reactive ion etching while using the active gas plasma. After eliminating the mask so as to form a light emitting layer, a metal electrode layer 101 is formed by deposition. Since the laminated metal material is divided by the groove 107 formed in the insulating film layer 109, the metal electrode layer 101 is securely formed into plural nearly band-like separated patterns.

Title: Inclusion evaluation method of maraging steel
Inventor: YAGASAKI TORU
IPC: G01N33/20
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To evaluate directly the magnitude of inclusions, and to improve greatly reliability of the maximum size of obtained inclusions by reducing dispersion caused by minute inclusions. SOLUTION: This method is an inclusion evaluation method of maraging steel, for calculating the maximum size of inclusions included in the maraging steel by an extreme-value statistical method. In this case, a sample of the maraging steel is dissolved in a solution to make only the inclusions remain in the solution. The inclusions remaining in the solution are filtrated by a filter having a prescribed mesh size to remove small inclusions. Sampling is executed relative to the inclusions remaining on the filter, and the maximum size of the inclusions is calculated based on the extreme-value statistical method.

Title: Digital/analog converter
Inventor: IMAMURA MAKOTO
IPC: H03M1/74
Filed: 1988-03-10
Abstract: PURPOSE:To prevent glitch by connecting a switching element in parallel with a current switch giving a current from a constant current source selectively to the 1st or 2nd line in response to an inputted digital signal so as to give forcibly the current from the constant current source to the 2nd line. CONSTITUTION:When a signal VOFF reaches a level sufficiently smaller than a threshold voltage VTH, transistors(TRs) 10-12 are all turned off and a digital signal is converted into an amplitude of a current being an analog signal. When the signal VOFF reaches a level sufficiently larger than the threshold voltage VTH, the TRs 10-12 are all turned on, the output current of constant current sources 1-3 flows to the 2nd line 8 and no current flows to the 1st line 7. That is, the output of the digital analog converter is zero. Thus, the signal VOFF, is brought into a high level before all bits of the input digital signal are changed, the signal VOFF is brought into a high level and brought into a low level after the change. Thus, no glitch is caused.

An annunciating part 3 is also connected in parallel with this control part 2, and with the switch 1 made into circuit, it is inputted into an annunciator 5 installed in the cage from a micro computer 4. A voice (for example, as we performs parking operation from now, so nobody gets in the cage because of stoppage at the first floor) and so on is emitted. In addition, it is outputted into the annunicator 5 for an inter val till stoppage of the cage is judged by a judging means since the switch 1 has been made into circuit by the microcomputer 4. Accordingly, such a fear that someone gets in the cage during parking operation and therefore might be confined and so on is preventable.

The width A of the developer concn. detection in the transparent conductive window member 34 is also greatly expanded. The detection of the developer concn. at the response speed capable of dealing with the variation in the developer concn. is, therefore, possible and is executable with high accuracy.
